Native Module configuration

Hi

I'm developing a native module for IIS7. I'm having difficulty understanding how to read in configuration data.  The module subscribes to the RQ_AUTHENTICATE_REQUEST, which gets called on every request, so I don’t want to have to load from a specific config file.

I’ve been using the following link as guide, but this example doensn't provide of an implementation.

If someone has an end to end example using IMetadataInfo that would be great.

Thanks, Craig
